How does Chapter 21 describe the ideal way to listen to stories about Sai Baba and the power of His words?

Chapter 21 begins by emphasizing the profound impact of Sai Baba's stories and the proper disposition for a listener. It posits that a speaker's words are in vain if the listener "does not sway upon hearing them" and if "the hair on the body does not stand on end." The narration is considered futile if the listeners are not delighted, their throats do not choke with emotion, and tears of love do not flow. This suggests that receiving these teachings is an emotional and spiritual experience, not merely an intellectual one. The chapter beautifully states that Baba's speech is "captivating" and His method of instruction is "extraordinary," highlighting the transformative power inherent in his words when received with an open and attentive heart.
